Members discussing the fuel economy of their Prado 150 3.0L D4D models. Fuel consumption varies widely depending on driving conditions, accessories fitted, and accuracy of the trip computer.
Observations
- Fuel economy figures reported range from 6.4L/100km (modified vehicle, possibly inaccurate reading) to 13L/100km+ (city driving, towing).
- Highway driving generally yields better fuel economy (8-10L/100km) than city driving.
- Towing significantly increases fuel consumption (13-19L/100km).
- Accessories such as bull bars, roof racks, and lifts negatively impact fuel economy.
- Trip computer accuracy varies; manual calculation (litres used / km travelled) is recommended for accurate figures. Some trip computers are optimistic.
- Fuel consumption may improve as the engine beds in (around 10,000km-20,000km).
- Speedo accuracy may affect calculations, comparing against a GPS is recommended.
- Tyre size and pressure affect fuel consumption.
Modifications Impacting Fuel Economy
- Tunit diesel computer: Claimed to improve fuel economy, but may make factory readouts inaccurate.
- 3" Genie turbo back exhaust: Possible contributor to improved fuel economy.
